Gold Nanoparticles: Colorimetric Detection of HIV‐1 Ribonuclease H Activity by Gold Nanoparticles (Small 10/2011)

The frontispiece of the Communications section (middle) features a low-cost and convenient approach to the colorimetric detection of HIV-1 ribonuclease H activity using unmodified gold nanoparticles. The method is potentially useful for screening enzyme inhibitors in drug discovery. For more information, please read the Communication “Colorimetric Detection of HIV-1 Ribonuclease H Activity by Gold Nanoparticles,” by X. Liu and co-workers, beginning on page 1392.
